Match the LIST-I with LIST-II.
| LIST-I (Type of Solutions) | LIST-II (Explanation) | ||
| A. | Isotonic solutions | I. | A solution in which no more solute can be dissolved at the same temperature and pressure |
| B. | Ideal solution | II. | Two solutions having the same osmotic pressure at a given temperature |
| C. | Binary solution | III. | A solution following Raoult's law over the entire range of concentration. |
| D. | Saturated solution | IV. | A solution consisting of two components |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A - II, B - III, C - IV, D - I
Each term in List-I describes a particular type of solution:
A. Isotonic solutions — This matches II. Two solutions having the same osmotic pressure at a given temperature. When two such solutions are separated by a semipermeable membrane, there is no net osmosis between them.
B. Ideal solution — This matches III. A solution following Raoult's law over the entire range of concentration. For an ideal solution, ΔmixH = 0 and ΔmixV = 0.
C. Binary solution — This matches IV. A solution consisting of two components. “Binary” means two, so the solution contains one solute and one solvent.
D. Saturated solution — This matches I. A solution in which no more solute can be dissolved at the same temperature and pressure. At this point, the dissolved and undissolved solute are in dynamic equilibrium.
Shortcut: The pair A–II appears in Options (1) and (2), and B–III then leaves only Option (1).
